'10 all whom it may concern:

Be it known that 1, JOHN R. Orsnm, citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Imrovement in Adjustable Supports or rackets, of which the following is a specification.

This invention relates to improvements in adjustable supports or brackets of the kind used for mounting mirrors on automobiles or vehicles in osltion to enable the driver 10 readily see 0 jects in rear of him. These mirrors are located at the front portion of the vehicle, and in the case of closed vehicles it is desirable to position the mirror inside of the vehicle and so as to give a view through the rear window thereof. In order to locate the mirror so that it will not obstruct the drivers view through the front window and will be out of the way, it is preferably placed above or adjacent to the upper edge of the windshield or front window, where it will be also inconspicuous and not unsightly when seen through the front window. It is important for the mirror to be adjustable so that it can be set atthe necessary angle horizontally and vertically, depending upon the location of the mirror in the vehicle and to suit the particular driver, in order to enable him to see the road or objects in the required rearward direction. The bracket or support for the mirror should be of a construction such that while permitting the above mentioned location and necessary adjustments of the mirror, it will be strong and stable and prevent vibration of the mirror so that the image reflectedby the mirror will be as nearly motionless as possible.

The object of this invention is to provide a practical and desirable mirror support or bracket for the pur ose stated, which is of simple, compact, sta 1e and inexpensive construction and is adapted to accomplish the results above mentioned.

In the accompanying drawings:

Figure 1 is anend elevation of a mirror support or bracket embodying the invention, showing the same mounted on the front bar of a vehicle top.

Fig. 2 is a sectional elevation thereof on I line 2-2, Fig. 1, looking toward the back of the mirror.

Fig. 3 is a plan view thereof showing by full and dotted lines difl'erent adjustments of the mirror.

Fig. 4 is a plan view of the adjustable bracket arm, detached.

Fig. 5 is a sectional view on line 55, Fig. 2.

Fig. 6 is an end elevation of a bracket of modified construction adapted to be removably clamped on the upper edge of a windshield or like support.

Fig. 7 is a plan view thereof, showing by full and broken lines different adjustments of the mirror.

Referring first to Figs. 1-5, A represents the mirror which may be of any suitable shape but which is preferably of relatively long, narrow shape and is provided with beveled edges.

The adjustable mirror su port or bracket comprises an outer or hol ing member or means 10 on which the mirror is removably secured, arms or members 11 and 12, to which the holding means or member is pivotally connected, and attachin members or means 13 and 14 adapted to fie fastened on the vehicle frame, or other suitable support 15. and to which the arms 11 and 12 are adjustably connected.

The mirror holding means 10 preferably consists of a single piece of sheet metal of substantially H-shape as shown, having parallel. upright legs 16. which are connected between their ends by a horizontal cross piece 17. The legs 16 are provided with bent or hook-shaped ends 18 adapted to extend around the upper and lower edges of the mirror and engage the beveled faces of the same. The mirror can be slipped endwise into place between the hooked ends 18 and secured therein by any suitable means. The means shown for this purpose consist of two screws 19 which pass t rough and trim in threaded holes in the holding memher back of the mirror and are adapted when tightened to press the mirror outwardly iloo against'the hogked ends 18 of the holdin member and thus firmly secure it in the hol ing member. In order to preventthe screws from contacting with and scratching or injuring the reflecting backing or coating of the mirror, bearing pieces 20 are provided having portions which extend between the ends of the screws and the back of the mirror. The bearing pieces shown are of U-shape and are held in place by passing through openings 21 in the holding member 10, and having in their inner ends holes through which the shanks of the screw pass loosely. The bearing pieces are thus retained loosely in place'on the holding member and are adapted to be forced against the back of the mirror by tightenin the screws. The ends of the screws hear an turn on the outer ends of the bearing pieces, which are pressed without turning against the back of the mirror and therefore will not injure the backing.

The adjustable arms or intermediate members 11 and 12 are pivotally connected to two perforated cars 22 which project rearwardly from the mirror holding member 10, preferably near its opposite ends. Each of the arms 11 and 12 prefer-ably consists of a sheet metal stamping having spaced, depending lugs 23 which embrace one of the cars 22 on the holding member 10 and are pivotally secured thereto by a belt or screw 24 passing through registering holes in the ear and lugs. Friction washers 25 of fiber or other suitable material are preferably placed between the lugs 23 and the opposite sides of the ear 22 so as to form a friction joint which will enable the mirror to be swung to different, angular positions but be held firmly by friction in the position to which it is adjusted. The forwardly projecting ends or portions 26 of the arms 11 and 12 lie substantially horizontally and are connected by screws or bolts 27 and 28' to the attaching means or member 13 and 14 of the bracket so as to permit horizontal adjustments of the arms 11 and 12 relatively to the attaching members to-set the mirror either parallel with or obliquely to the support 15. In the construction shown in Figs. 15, the forward end of the arm 11 has a pivot hole through which the screw 27 for this arm passes so that the arm can turn horizontally on the screw as a pivot, while the forward end of the other arm 12 is provided with an elongated slot 29 for its screw 28, preferably concentric with the pivot 27 for the arm 11, so that the latter arm 12 is ada ted to be adjusted forwardly or rearwar ly on its attaching member as may be necessary to set the mirror in the desired relation to the support '15. As indicated in Fig. 3, the arm 12 can be adjusted forwardly or rearwardly on its attaching member to adjust the mirror to a greater or less angle to the support- 111;; bar. The attaching members can be secured by screws or other suitable'fastenings to the supporting bar 1!}. Each of the members 13 and 14 shown is provided with upper and lower, spaced lugs 30 between which the forward end of the related arm 11 or 12 is clamped, and friction washers 31 of fiber or other suitable material are preferably employed between the lugs 30 and the oppo- 'site faces of the interposed end of the arm so as to give the necessary friction to properly hold the arms in the position to which they are ad'usted.

The brac et shown in Figs. 6 and 7 is similar to that above described except in the following particulars.

This bracket is intended for removably amounting the mirror on the upper edge or frame bar of a windshield or analogous sup port 32, and for this purpose the attaching members are in the form of clamps adapted to embrace and grip the frame bar 32. Each clamp shown comprises opposite jaws 33 and 34 connected by a clamp screw 35. One member 34 of each clamp is provided with a projecting, substantially horizontal hi or portion 36 to which the forward end 0 the related, adjustable arm 11' or 12" of the bracket is adjustably secured by a screw '37. In this construction each of the arms 11' and 12 is provided with an elongated slot 38, see Fig. 7, each slot being concentric with the screw for the other arm. In this way either of the arms 11 or 12 can be ad justed forwardly or rearwardly on its attaching clamp, as may be required to give any desired horizontal obliquity in either direction to the mirror. Since the clamp is not provided with spaced lugs between which the forward end of the adjustable arm is adapted to be clamped, but with only one projecting lug, a clamping washer 39 is preferably employed between the head of the screw 37 and the forward end of the adjustable arm and this washer is provided at one side with a bent In 40 adapted to engage the edge of the ad ustable arm, or with other means for preventing thewasher from turning. Friction washers 41 are also preferably "used in this constructionas in the others, at opposite sides of the front end of the adjustable arm to give the necessary friction in the joint.

Both arms 11 and described can be slotted, as in the case-of the bracket shown in Figs-6 and 7 if desired.

In both of the constructions described the mirror is supportedby two adjustable arms located near the ends of the mirror. or at a considerable distance apart. The mirror is therefore, held very rigidly or firmly an the vibration thereof prevented. Nevertheless, the brackets or supports constructed as described enable both the vertical and horizontal ad'ustments'neeessary to set the mirror in tli -erent,'required positions.
